| subcutaneous fat necrosis of newborn | Indurated plaques and nodules appearing usually a few days or a few weeks after birth and usually resolving within a few months, characterised microscopically by birefringent needle-shaped crystals within necrotic fat cells; the condition remains localised, unlike sclerema neonatorum.

| infant, newborn, diseases | Diseases of newborn infants present at birth (congenital) or developing within the first month of birth.

| jaundice of the newborn | Icterus which can be accentuated by many factors including excessive haemolysis, sepsis, neonatal hepatitis or congenital atresia of the biliary system. Synonym: physiologic icterus, jaundice of the newborn, neonatal jaundice, physiologic jaundice. (05 Mar 2000) |
| leukocytosis of the newborn | An apparently "physiologic" leukocytosis usually observed in newborn infants, in whom the white blood cell counts are usually greater than 10,000 per cu mm, and sometimes range to 45,000 per cu mm, resulting chiefly from increased numbers of neutrophils (especially single and bilobed forms). On the third or fourth day of life, the count generally decreases rapidly, and then fluctuates for several days; beginning about the fourth week of life, a relative lymphocytosis is observed, and this normally continues for a few years.

| median umbilical ligament | <anatomy> The remnant of the urachus, contained in the median umbilical fold; it persists as a midline fibrous cord between the apex of the bladder and the umbilicus. Synonym: ligamentum umbilicale medianum, middle umbilical ligament, urachal ligament. (05 Mar 2000) |

| prolapse of umbilical cord | Presentation of part of the umbilical cord ahead of the foetus; it may cause foetal death due to compression of the cord between the presenting part of the foetus and the maternal pelvis. (05 Mar 2000) |
